    int arr[4];
    foo(arr);

We can look at this code like it passes an array by reference, but how to pass `arr` by value?

You can pass it by value when putting it into a struct. You can also pass a pointer to the array instead of letting it decay.

void foo(int (*arr)[4]);

int arr[4]; foo(&arr);
